PATENT @rrrcn HEATING-DRUM FOR OIL-STOVES.

SPECIFICATION forming part of Letters Patent No. 778,683, dated December27, 1904.

Application filed January 7, 1904. Serial No. 188,141.

To all whom, it may concern:

Be it known that I, J OSEPH CASPER KULP, a citizen of the United States,residing at Farmingdale, Monmouth county, New Jersey, have inventedcertain new and useful Improvements in Heating-Drums for Oil-Stoves, ofwhich the following is a specification.

The object of my invention is to construct a device of cheap and simplecharacter whereby the flame of an oil-stove, lamp, or gasburner may beeffectively used for heating the air in a room or apartment. This objectI at tain in the manner hereinafter set forth, reference being had tothe accompanying drawings, in which Figure 1 is a vertical section of aheatingdrum for oil-stoves constructed in accordance with my invention;and Fig. 2 is a sectional plan view on the line (a a, Fig. 1.

Many different forms of radiating devices to be heated by the flame ofan oil-stove, lamp, or gas-burner have heretofore been proposed; and theobject of my invention is to oheapen and simplify the construction andincrease the efliciency of such devices.

As shown in the accompanying drawings, my improved radiator is composedof upper and lower drums 1 and 2, which are in free communication witheach other, the upper drum being closed at the top and being of largerdiameter than the lower drum, a horizontal annulus 3, with perforations4, connecting the two drums. The lower drum is open at the bottom and ismounted upon suitable legs 5 or other desired supports, which also serveto support the bowl or font 6 of the lamp, the latter being so disposedthat its burner portion projects upwardly into the open lower end of thedrum 2, which is preferably provided at the bottom with a flaring flange7 for directing the air inwardly toward the burner of the lamp. The drum2 also has on one side a glazed opening 8, through which the flame ofthe lamp can be seen.

The flame from the burner of the lamp rises in the drum 2, as shown,said drum serving as a chimney for the lamp and soon becoming highlyheated, as do also the top and walls of the upper drum 1. Twoindependent means of heating the air in the room are thus provided, thefirst being the direct radiation from the highly-heated walls of thedrums 1 and 2 and the highly-heated top of the latter and the secondbeing the air heated by direct contact with the flame of the lamp, whichafter rising through the drums 1 and 2 is directed downwardly adjacentto the outer walls of the upper drum and escapes into the room throughthe perforations 4L in the annulus 3.

The aggregate area of the perforations 4: is considerably in excess ofthe area provided for inflow of air at the lower end of the drum 2, sothat free escape of the expanded .air and products of combustion throughthe perforations a is permitted and there is no obstruction of the draftof the lamp.

It will be evident that a heating device of the character described isof extremely cheap and simple construction, and I have found in practicethat it is very effective as a means of heating a room or apartment, thedownward discharge of the heated air from the perforations 4: beingdirected toward the floor and carrying with it the heat radiated fromthe walls of the lower drum 2. Hence the heat is applied at the mosteffective point for accomplishing the proper heating of the air in theroom.

Although I have described my invention as used-in connection with anoil-lamp, it will'be evident that a gas-burner might be used instead ofthe lamp, if desired.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. A lamp-heated radiator, consisting of a pair ofsuperposed vertical drums, in free communication at their point ofjunction, the upper drum being of larger diameter than the lower drum,and the walls of both drums being exposed directly to the air of theroom or apartment to be heated, the upper drum being closed at the top,the lower drum receiving the flame from the burner at the bottom, andthe two drums being connected by a perforated annulus, through which theair heated by direct contact with the flame is caused to flow downwardlyfrom the outer portion of the upper drum, substantially as specified.

2. A lamp-heated radiator, consisting of a pair of superposed verticaldrums, in free communication at their point of junction, the upper drumbeing of greater diameter than the lower drum, and the Walls of bothdrums being exposed directly to the air of the room or apartment to beheated, the upper drum being closed at the top, and the lower drum beingopen at the bottom for receiving the flame from the burner, the twodrums being connected by a perforated annulus,through which 10 the airheated by contact with the flame of the lamp is caused to passdownwardly from the outer portion of the upper drum, the area of theoutlet through said annulus being in excess of the area of air-inlet atthe bottom of the lower drum, substantially as specified.
